AdministratorCalculate total column value in power query
Hello everyone, I have a situation, I want to assemble a column of cumulative total of the value of the column "Rs" to be able to take an average of it.
This is the way I want to visualize it but it is calculated automatically because it comes from a database that they constantly update.
Thank you very much, I hope
Hi ，
Please have a try.
Click on the 'Add Column' tab in the ribbon, and then select 'Custom Column'.In the 'Custom Column' dialog box, enter a name for the new column (e.g. 'Cumulative Total').In the 'Custom Column' dialog box, enter the following formula:
= List.Sum(List.FirstN([Rs], CurrentRowIndex + 1))This formula calculates the cumulative total of the 'Rs' column up to the current row.
Once you have created the cumulative total column, you can take an average of it by selecting the column and clicking on the 'Average' button in the 'Transform' tab of the ribbon.
